FAQs: Voice & Video Calling

How do video APIs work?

A video call API or voice call API lets you embed real-time communication into your app or website. It connects users through secure peer-to-peer or server-based calls using WebRTC and a backend infrastructure.

What is a calling SDK?

A calling SDK—like a voice chat SDK or video chat SDK—gives developers everything they need to add high-quality voice and video features into apps. It includes built-in UI components, connection logic, and security protocols.

What is the difference between a video calling API and video chat SDK?

An API for video calling is a set of tools that enables apps to make video calls. A video chat SDK provides prebuilt components and functions to simplify integration, saving developers time and effort. QuickBlox video chat SDKs support the use and integration of our video calling API to create an innovative audio and video calling solution.

What is the difference between video calls and video conferencing?

Video calls connect users directly (peer-to-peer) and are ideal for small groups. Video conferencing uses a media server to support larger groups, making it more scalable but also more costly.

What is WebRTC?

WebRTC (Web Real-Time Communication) is an open-source technology that enables real-time voice, video, and data sharing directly in web and mobile apps—no plugins required. It powers QuickBlox’s video call API and voice chat SDK solutions. As the leading standard in video technology, you can be confident of building secure high-performance video chat applications.

Does your video calling solution work on mobile apps?

Yes. Our video chat SDKs support Android, iOS, and web, with cross-platform options for Flutter and React Native. Whether your users are on desktop, tablet, or mobile, we’ve got you covered!

How do I integrate video calling into my website?

You can add video calling to your site using a video chat API or video call SDK. Just install the SDK, follow the documentation, and customize it to match your UI. QuickBlox offers a comprehensive video calling solution.

Can I add chat features to my video chat application?

Yes! You can easily add real-time messaging to your video calling app using our cross-platform Chat APIs and SDKs. We also provide code samples to help you integrate quickly.

Can I host video chat on-premises?

Yes. With QuickBlox you can host our software in our managed public cloud, within your own private cloud, or on premises. Find out more about our hosting options.

How much do video calls cost?

Video calls made with our SDKs are peer-to-peer, so there’s no extra charge for call minutes. Our video chat SDK handles signaling only (to start, update, or end calls), and these signaling messages count toward your monthly storage and traffic allowance.
